Class
    Foam::radiationModels::sootModels::mixtureFraction

Description
    This soot model is purely an state model. The amount of soot produced is
    determined by a single step chemistry as :

        nuf Fuel + nuOx Ox = nuP P + nuSoot soot

    nuSoot is prescribed by the user.

    The single step chemistry used is read from the combustion.
    The soot is not considered into the thermodynamics of the system and it
    is not considered as an extra specie in the solver.

    The spacial distribution is given by the normalisation of the first product
    on the rhs of the reaction by default or it can be added as input.

    For example in the radiationProperties dictionary set:

    sootModel mixtureFraction;

    mixtureFractionCoeffs
    {
        nuSoot              0.015;
        Wsoot               12;
        mappingField        P;
    }
